Positive polymer fecal sludge treatment apparatus

Abstract

A positive polymer fecal sludge treatment apparatus comprising a trash separator, one end of which is connected with a sludge inlet, and the other end of which is connected with a twin-rotor vacuum water pump. A high-pressure transparent tube is disposed and connected, by a knife valve, between the trash separator and the twin-rotor vacuum water pump. One end of the knife valve is connected with a first material box and a second material box. A first chemical box and a second chemical box are disposed under the first material box and the second material box, and each of the first material box and the second material box is connected with the first chemical box and the second chemical box. The first and second material boxes have a larger volume than a conventional one and thus can store more material and also can perform chemical stirring reaction directly.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention belongs to the field of wastewater treatment technology and in particular relates to a positive polymer fecal sludge treatment apparatus.2. Description of the Related Art[0002]Fecal sludge refers to wastewater flushing feces of human during daily life, which is defined as domestic wastewater containing feces substances, for example, toilet wastewater and feces medium in toilets. The fecal sludge is a typical high-concentration organic wastewater for which the basic treatment task is to remove various organic matters therein. The current fecal sludge treatment method is a biological treatment method by which those organic matters in dissolved or colloidal state in the sludge are degraded by vital activities of microorganisms so as to purify the sludge. However, the apparatus of the method occupies a larger area, has a demanding temperature requirement, and takes a longer time of treatment with a lower tre...

AI Technical Summary

Benefits of technology

The present invention provides a positive polymer fecal sludge treatment apparatus with high efficiency and high speed. It uses a trash separator, a vacuum pump, and a transparent tube for efficient treatment. The apparatus includes two material boxes, two chemical boxes, and a mixing box for quick and uninterrupted operation. The two chemical boxes can work alternately to realize faster chemical reaction and cleaner water discharge. The apparatus also includes a multi-disk screw press for cleaner and drier treatment of fecal sludge. The numerical control operation box enables timed charging and operation in a given amount. The apparatus can achieve full automatic operation and is advanced compared to manual or semi-automatic operation. It also allows for washing and has a large quantity of water sucked and discharged.

Problems solved by technology

However, the apparatus of the method occupies a larger area, has a demanding temperature requirement, and takes a longer time of treatment with a lower treatment efficiency.
